The [Seaforium Booster] is in a crate in a zeppelin crash site in Dustwallow Marsh. The crashed zeppelin is notoriously hard to find and get to. It is up against the mountains which lie on the eastern coast of Dustwallow Marsh. The section of mountains cradle the zeppelin crash like a backwards C. The area of the crash is called Beezil's Wreck. The seaforium booster can be found in a box near the crash. Coordinates (54,56).
